Building a Space Elevator: gotta start somewhere

Can't believe the weather at the moment - despite an official drought in this (and other) regions, it's been tipping it down the best of a week. The only bright side to this is it means my backlog on the CCTV analysis might not be as insurmountable as it currently seems! 

Not so great for the bumbles though - they've not had a lot of time to get out of the nest! And then they have it's been pretty short trips, often getting caught out by showers. It's been horrible to see them coming back wet, because, of course, it takes them longer to get into the nest via the flap than it would do otherwise (the queens especially have the most trouble). I suspect we have actually lost quite a few - it's one of my usual hunches, which i now rely on to be generally right (they are!) - based on a sense of how many are going out versus returning.

There's not actually a lot of pollen out there either - the rape seed fields have blossomed but the local ones are probably too far for our bumbles to get to from here. There's some dandelion on the roadside - but I had to say, they are doing well to get what they're getting!

All the rain is causing a bit of a backlog in the nest for bumblebees - in particular, queens - waiting to get out. They seem to like the inside front of lodge for waiting/resting. We're not sure why - whether they can sense the outdoor temperature through the wood; or the vibration of the rain; or feel the heat of the sun; or perhaps the warmth from the infra red camera. Anyway, here are some pics

Queens stacked up waiting to get out!It's not just queens of course - here are some workers for comparison - a few fanning too.. These are large workers, but the size different is still obvious.

She seems to have a lookout role but also blocks the others (especially the larger ones) from leaving when the weather is not good. She sits there overnight too - right up against the entrance. In fact she often pushes against the wax moth flap to open it slightly, apparently to sense the air/weather. We are still trying to figure out exactly how they sense temperature, because we know this controls the leaving patterns in the morning. Here she is:

 

 

Building Bridges

We noticed yesterday that bumbles at the back of the nest, right under the camera, were climbing up some kind of self-made "pole" from the floor of the nest to the first lip (maybe 4 - 5 inches). It's hard to figure out how this construction has come about, because for a while it looked just like the end of a piece of "stuff" lying flat on the base of the nest-tub and protruding into the picture. It got shunted around a bit, then something happened overnight, and next thing we know it's being used like an elevator to get from the floor of the box to the top of it! We can definitely see bees shimmying up and down it quite consciously and occasionally "fixing" it (i.e. messing with it) at the bottom.

It's a bit hard to see in the picture (the video always seems clearly than the stills) but it comes up from the floor in the middle left:

The Internet of Bumblethings - Tech Update

We've always had a strong technology angle on our project - if nothing else, it has made the whole thing far more enjoyable by allowing us such intimate observation in the lives of these amazing creatures. But actually, more than that, it has allowed us some fascinating observations and data collection that sheds (some possibly new) light on their normally private and underground existence. 

A lot is known about bumblebees, but that doesn't mean everything is - and particularly as the climate and macro and micro environments change, so too bumblebees are surely affected. So, we feel that observing, collecting data and reporting our findings is also an important part of our project - and the technology is a big part in that.

There's a fun side to it too - From the outset I've wanted an internet connected bumblebee nest (see Internet of Things), so that we can remotely monitor data, but also do fun things, like have the bumblebees send tweets. This kind of technology, while seemingly frivolous, is actually an important part of our future, in terms of environmental understanding and monitoring. It's the kind of technology that is monitoring habitats, storms, oceans, tidal waves, severe weather and so on. Someone has to explore the "art of the possible" so that we can understand and predict our planet better. 

For our first year I dabbled a bit with some "interconnectedness" - got a few tweets coming out of the CCTV system when it detected movements, but it really was dabbling round the edges. I was also comtemplating a new system called "Twine" which provides temperature and movement detection in a small plastic "soap bar" that can connect to the internet. But it's expensive.

For this year, however, I'm excited to discover iobridge. This clever little modular system connects to your network and internet and a whole range of different types of sensors. You can easily configure its operation and rules through the iobridge website and cloud service, as well as get the system integrated with other webservices, and of course twitter :-) 

iobridge - creating the "internet of things"I plan to document what I'm doing with this on my technology page rather than within the blog, so it's all in one place. 

Suffice to say, there are a lot of possibilities with a connected bumblebee nest, for example:

 

  • warnings of temperature too high / too low
  • measuring activity levels and correlating with weather and light
  • measuring light levels and entrance / exit behaviour
  • counting bumblebees in and out

 

The beauty is, all this data can be published on an online dashboard, viewed on the iPhone/iPad and also integrated with other services, as well as sending alerts and messages via email and twitter etc. There really is huge scope to monitor and collect some great data, and completely automate the process. I can even embed some of the realtime data in other websites, such as this blog. 

I've been making good progress so far getting it configured. For example, I have an LED which is green before sunset and red after sunset (so we know when the bumbles should be in), a small alarm that goes off if the temperature gets above 30C (and tweets some warnings in advance), and I'm currently working on counting the breaks in a light beam so we can start to count the bumbles coming and going. 

Can't wait to get it all hooked up in situ!

Fat Bottomed Girls - and our 1st goodbye

We've had a few bumblebees in care now, 3 in fact, all very small and missing various bits such as wings and legs. They've been getting along great together in their box and feeding well. Here they are all sleeping/resting together - very cute ☺

3 tiny bumbles resting overnightOnce BCW was back from her travels she decided to name them after the 3 Amigos (3 Abeegos, as I call them): Lucky, Dusty and Nedine (girl's version of Ned). 

Sadly, girl/worker bumblebees generally have a very short life, perhaps 1 - 3 weeks, and the small ones especially so. Lucky, the first one I rescued, took a turn for the worse mid morning - very still and listless. We offered her some honey water but she wasn't interested and it didn't help to revive her. 

Little Lucky - not feeling so wellIt looks like this evening we've lost her; sad indeed, but we are becoming used to it - all part of the short cycle of life for bumblebees and for her only perhaps 6 - 10 days old.

I've not had chance to scan the CCTV so far this week (which is not good) - but it's been so wet and windy that there's not been a lot of activity. One of the most intriguing things we'e seen is what seems to be a queen fanning. I'm surprised she is taking on a worker role. I keep doubting if it's a queen, but here's a series of pictures and I'm sure that all the large bees are queens. Indeed, some of them are easily over 25mm in length.

Weekend Update 2

It's pretty much been a bumble-filled day today (sunday) as well. I was determined to catch up on as much as possible. 

Updates to observations

The observations page will probably never be finished, but it was definitely lacking a few items I'd forgotten and some photos and videos. So, I've added some information about trip times, some more video and some extra pictures plus a few other bits and bobs. 

New Tumblr

I decided I wanted an immediate way to share photos, especially those taken in the field, just as a way to get more close up and personal with the lives of our bumbles. Although I can upload to this blog via the iPhone it's not really quite as immediate, and you don't necessarily want to write an article for just a single picture). So, I've created a tumblr page at www.lovebumblebees.com 

More Data

Sometimes life feels like a constant stream of data - mainly because most of my data capture is manual at the moment (though improving in areas). So, I'm constantly playing catch up and this weekend was no different. However, I've managed to skim another 2 full days of CCTV and count all the trips and new memorisation flights. 

So, for 18th and 19th April in our beepol nest (2012B1) we have:

 

  • total trips = 275
  • total memorisation flights = 44
  • total Queen trips (included in above number) = 18
  • total Queen memorisation flights (included in above number) = 7

 

If we add this to existing data for the first two days, it gives us a total of 180 memorisation flights (i.e. colony of at least 180 workers) and 12 Queen Memorisation flights (thus we assume 12 new queens!)

WOW!

Another Patient

I went outside today to cut the grass and just before I did so checked the live CCTV for anything nearby. Lo and behold a small bumble struggling to fly. I went to her rescue and tried to help her to the nest, but she was determined to make a break for it and fell to the floor. I decided I should rescue her and add her to the two we already have indoors.

She has the same disabilities as one of the others - exactly the same leg and wing not developed, so she cannot fly. She's slightly larger though. I added her to the box with the others and all seems to be going well. From what I have seen they are all having a good drink as required.

Changing the bedding

I was at home by myself today so I spent most of it writing up a new page, summarising key observations from all our bumblebee studies. There are a lot and although they are all contained in this blog somewhere, you'd never be able to piece them together. So the page is long overdue. 

It's again been a showery day on and off, so the bumbles have been thwarted. This girl spent most of the day in the entrance stopping the others from leaving (yes, even the big queen!):

Our two little indoor invalids (secretly I'm calling them pinky & perky, but they're not official names) are doing fine, drinking plenty and general mooching along fine:

I did attempt some macro photography using my zoom lens and macro extension tube - here's the setup:

It turned out to be completely useless (which is why they invented macro lenses), though it did but my tripod through its paces (that kit is HEAVY) and momentarily scared me. ☺

Despite best intentions I got no chance at all to review CCTV so I have a massive backlog of 5 days. Eek. but I kept an eye on the nest - really not a lot happening new today.

Tonight however, this bunch of bees have gone nuts over re-arranging the bedding under the camera. Don't know why, and I certainly wish I knew how they co-ordinated themselves on it and what they want to achieve. So, I've been taking lots of before and after shots:

"before""after"I'm trying to work out which pots are sealed - because some are empty and not sealed (centre bottom) and some are honey filled (easy to see with the catchlights). The seal pots will contain eggs and so may hatch at a later date. So, one theory is they are dragging the bedding to cover the sealed pots and keep them warm (30C). Just going to have to keep an eye one what happens under that bedding over the coming days / weeks!
